Looks a lot better!
It's too bright though, that happens very fast if you use multiple uber clouds. I usually use darker tinted uber clouds (the RGB values are under 100), it tends to turn out better if you use more dark clouds instead of a few bright ones.
And use different variations so they don't clump together in certain areas. I'm using the trial-and-error method and just place+delete them until something satisfying pops up.
